METHOD OF AND DEVICE FOR CHECKING THICKNESS OF COATING OF CYLINDRICAL ARTICLES Russian patent published in 2006 - IPC G01B15/02 

FIELD: mechanical engineering; coating thickness checking devices.

SUBSTANCE: according to proposed method, X-ray radiator and n detectors are installed in common cross-section of article, but on its different orbits. Detectors are arranged on first orbit at distance from center of article equal to (1.2-1.5)R where R is radius from center of article to interface between coating and base of carrying material of article, being equally spaced at arcs of sectors formed by radial sections passing through center of article and n detectors and square to cylindrical surface of article, and X-ray radiator is arranged on second orbit remote from center of article at a distance of (1.8-2.2)R and is displaced in circumferential direction along its orbit in steps equal to length of arcs of sectors formed by radial sections passing through center of article and n detectors, article to be checked being uniformly moved along its longitudinal axis.

EFFECT: provision of continuous check of thickness of coating made of different material over entire surface of cylindrical article in process of application of coating.
